When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?
When two alleles of a pair are identical, it is referred to as homozygous. When the two alleles are different, it is referred to as heterozygous. Homozygous individuals have two identical alleles (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa).
How do chromosomes pair up during the process of mitosis or meiosis?
During mitosis, chromosomes pair up by replicating and aligning themselves in the center of the cell before separating into two identical sets. In meiosis, chromosomes pair up in homologous pairs, exchange genetic material, and then separate into four non-identical sets of chromosomes.
What are a pair of genes that are identical called?
A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.
Which homologous chromosome pair in humans is the only one that is not identical?
The only homologous chromosome pair in humans that is not identical is the sex chromosomes, specifically the X and Y chromosomes.
Is A heterozygous pair of alleles is identical?
When there are heterozygous alleles for a gene thy code for a different expression of the gene. For example, the gene to taste PTC paper is a single gene trait. A person will have two copies (or alleles) for that gene (one from their mothers DNA, one from their father). There are two possible expressions for this gene - either you can taste the chemical or you cannot. When one allele is for tasting, and the other for not tasting, this is known as heterozygous. Both alleles are relating to the same gene but they giving different instructions and are thus not identical. When this happens, the dominant gene wins - in this case tasting is expressed. If the alleles are identical, they are known as homozygous and they are identical.
When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?
When two alleles of a pair are identical, it is referred to as homozygous. When the two alleles are different, it is referred to as heterozygous. Homozygous individuals have two identical alleles (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa).
What might you call two identical fruit Homophones?
Pair pear
What types of allels are expressed only if two identical copies exist on the homologs of the offspring?
A recessive gene A recessive gene makes it harder for genes(or traits) to be passed on from parents to daughters.
How many phenotypes are possible from complete dominance allels?
Two
What is a pair?
A pair is two persons or items that are similar in form or function, such as a pair of shoes or a pair of chairs. A pair is also a single object with two joined similar parts for a single function, such as a pair of pants or a pair of scissors.
How can a person receive two different allels?
By raping each other.
Are quadruplets always identical or always fraternal or can they be either?
Quads can be identical, fraternal, or a pair of identical twins. Identical quads are rare- that would require 1 egg divide into 2, and then divide again into two. Most quads are fraternal.
What is a organism that has two different allels for a trait?
an organism that has two different alleles for a trait is heterozygous
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
Explain why a trait inherited by incomplete dominance is not a blend of two allels?
sex
When a pair of chromosomes contains different alleles for a trait that trait is called a what when a trait has two identical alleles it is called?
2 different alelles - heterozygous Same alelles - homozygous
Which pair of dates is identical?
Identical pairs of dates are those that have the same month, day, and year.
